Bzart Set "Best Before" Date

I just received my Bzart Set (includes the following):

• Bzart Geuze Cuvée 2011

• Bzart Triple Forte 2013

• Bzart Kriek Cuvée 2011

• Bzart Session Triple 2013

Interestingly, each bottles says "improves with age." Each beer was also apparently aged 13 months, from what I can tell from the label. Each also appears to have been bottled around the same time, November 2014.

However, and to my point, "improves with age" doesn't mean it will age forever. (A mistake that I'm guilty of! I seem to keep a lot of beer in my cellar way! to long). Each bottle for each style also has a "Best Before" date of November 2020. Meaning, even the producer wants us to drink these offerings in the next 6 years.

The foregoing simply for information's sake.
